Specification of Letters Patent.

Patented June 28, 1916.

Application filed June 3, 1809. Serial No. 499,951.

To all whom it may concern:

Be it known that we, JOHN SELLERS BAN- onorr and MAURrrz C. INDAHL, ofPhiladelphia, county of Philadelphia, State of Pennsylvania, and usefulImprovements in Low Quad Molds for Type-Machines; and we do herebydeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, forming a partof this specification, and to the figures of reference marked thereon.

The present invention relates to improvements in molds for type machinesand espe cially to the class known as low quad molds for automatic typecasting and composing machines, and it'consists in the construction,combination and arrangement of parts hereinafter fully described, thenovel features being pointed out in the claims.

In the accompanying drawings illustrating a preferred form ofembodiment-Figure 1 is a perspective view of the mold. Fig. 2 is a rearend elevation. Fig. 3 is a transverse vertical sect-ion on the line y-y,Fig. 6. Fig. 4 is a vertical section on the line 3-3, Fig. 6, unitingthe point block. Fig. 5 is a partial sect'on corresponding with Fig. 4,omitting the main or lower mold blade section. Fig. 6 is a horizontalsection on the line 20 02, Fig. 2. Fig. 7 is a view in perspective ofseveral parts of the mold detached and separated one of the side blocks,the mold blade, and some of the screws being omitted. Fig. 8 is aperspective view of the main or lower section of the mold blade. Fig. 9is a perspective of the upper or cutoff section. Fig. 10 is aperspective of the head for the cross-pin. Fig. 11 is a perspective ofthe cut-off section looking from the end and side opposite Fig. 9. Fig.12 is a detail sectional view through the front stop or gage. Figs. 13and 14 are diagrammatic views showing the-jet slide in two positions ofadjustment.

Similar numerals designate like parts in the several views.

To the base plate 1, provided with the usual nozzle seat and jet opening2, is adjustably secured an integral squaring block 3, the latterfurnished with accurately dressed gaging surfaces 4 in planes at righthave invented certain newangles to receive the side blocks 5, 6. Thesquaring block 3 is secured to base plate 1 by bolts passing throughelongated openings permit-ting adjustment, the latter being effectedthrough the agency of two or more pairs of screws 7 8, the members 7 ofone set entering the squaring block with their heads overlapping andengaging the base plate and those of the other set 8, entering the baseplate and overlapping the squaring plate in a manner well understood. Tothe base plate 1 opposite and in parallel with the inner edge ofsquaring block 3 is erected the front abutment, prefenbly constructed insuperposed sections 9, 10, the upper section 9 overhanging or projectingbeyond the lower section on the inner side thereof to form a top bearingand provided with a longitudinal recess for the reception of a shoe 11,the latter backed up by adjusting screws 12. Side blocks 5, 6, areadjustably secured to squaring block 8 in the angle be tween its gagingsurfaces 4, as by screws 13, the inner edges of said blocks overlappingthe inner edge of squaring block 3, as indicated in Figs. 1, 4, 6 and 7.The crossblock 14 has attached to the side next the front abutment 9,10, a wearing plate 15 provided with a lateral off-set or rib 15 Figs.1, 4 and 6, projecting beneath and engaged by the overhanging portion ofabutment section 9, and to the lower surface of said cross-block aresecured the jet blocks 16, Fig. 7 the latter extending beyond thecross-block and contacting with the inner edge of the squaring block 3beneath the overhanging portions of the side blocks. The jet blocks 16are disposed in sequence longitudinally of the cross-block and separatedto form a transverse channel for the ejector blade 17, the end of saidchannel next the squaring block constituting the jet opening throughwhich molten metal is injected into the mold cavity above. As thusconstructed and arranged the cross block is maintained in workingcontact with the side blocks by adjustable shoe 11 and is held down toits seat on the base plate 1 on op posite sides, that is to say, by itsengagement beneath side blocks 5, 6, on one side and by the top bearingfurnished by section 9 on the opposite side, whereby lateral tilting ofthe cross block in a direction to open the joints in the mold cavitybetween the side blocks and cross block and the consequent distortion ofsaid cavity by throwing the face of the cross block out of parallelismwith the mold blade is prevented.

The gate pusher 17 is grooved in its lower edge to receive the cam 18fast on the base plate said cam operating, as the cross block isreciprocated, to effect a longitudinal motion of the gate pusher fordischarging the gate. Heretofore the base plate was perforated to form apassage for the gate when discharged by the pusher, but it sometimeshappened that the gate or jet would become lodged in the passage andobstruct the cross block, besides which the presence of said opening inthe base plate complicated in a measure the ever present problem ofcompensation and adjustment incident to variations in temperature. Thesedefects have been cured by cutting away the corner of the squaring block3, as at 19, Figs. 6 and 7, and recessing the base plate 1, as at 20,and locating the off-set section of cam 18 in such relation that thegate or jet will be dis charged in rear of the shoulder 21, so thatshould the jet hang up or adhere to the cross block it will be engagedand removed by shoulder 21 upon the return of the crossblock, and bedischarged over the edge of the base plate instead of through thelatter. Side blocks 5, 6, are spaced as usual, to form the mold bladechannel, by an interposed gage, 2'. 6., point block 22 corresponding inthickness with the point dimensions of the bodies of the type to beproduced, a tie bolt 23 assisting in retainin the blocks in contact withthe point bloc The lower or main section 24 of the mold blade does notdiffer essentially, save as to height, from the integral mold bladeofthe prior art, and is provided with the three regular openings to-wit25 for the point block 22, 26, for the front stop 27 and 28 for thecross pin 29, the latter carried by the cross head 30 of the mold bladeadjusting devices or mechanism.

The principal improvement in the mold blade resides in the equipment andapplication of the upper or cut-off section 31. The operating portion orthat part overlying the casting end of the main section and occupyingthe upper portion of the mold blade channel adjacent the mold cavity isnecessarily of reduced dimensions and liable to be displaced or sprungand thus open the joint between it and the main section, to the seriousimpairment of the functions of the mold blade.

Owing to the fact that the die case has its movement in close proximityto the top of the mold it is not permissible to materially increase theheight of the latter as by the application of superposed guiding devicesfor the cutoff section, consequently attempts have been made to controlsaid section from below the upper surface of the mold and in rear of theside blocks, either by providing a beveled lateral extension on thecut-off section and a complemental undercut guide on the side block, byproviding said section with a. vertical extension or web in parallelwith the main section in rear of the side blocks; by reducing thelateral dimensions of each section to one half or less of the width ofthe mold blade channel and disposing the reduced portions side by sideWithin said channel; or by combinations of the above. There areobjections to each of these schemes. The beveled side bearing is bothdifiicult to make and to maintain in adjustment; the narrowing of themain section for the accommodation of the dependent web of the cut-offsection not only increases the difiiculties in the way of fitting but italso diminishes the strength and rigidity of the main section and itsbearing in the mold blade channel; while the hearing afforded by thevertical extension of the cut-off section in rear of the side block istoo remote to be completely effective unless an excessive degree ofpressure is applied such as tends to retard the free movement of thecut-off section relatively to the main section.

The foregoing as well as other inherent defects in the prior structures,have been overcome by the following construction. The upper or cut-offsection takes its bearing upon the upper edge of the main section, tothe full Width of the latter, from the casting face to a point in rearof the point block opening 25, Fig. 4, "and said section is attached toa carrier 32 of substantial proportions, the latter disposed to one sideof the mold blade channel and guided to reciprocate in a way formedbetween side block 6 and main section 24 of the mold blade. Cut-offsection 31 and carrier 32 may be integral; but it is preferred to formthe cut-off section with a lateral flange or rib 33 the latter fittedand fastened to the top surface of carrier 32 to permit a carrier ofstandard dimensions to be used in connection with cut-off sections ofdifferent point dimensions.

To afford an extended bearing for the rear end of the mold blade,squaring block 3 is provided with a rear extension or offset portion 34,the upper face of which is in a plane below but parallel with the topsurface of the squaring block, 71. 6., the lower surface of the moldblade channel. The rear end of carrier 32 is off-set as at 35 to take abearing upon said extension 34 and is supported laterally between twoadjustable guides or plates 36, 36*, secured to extension 34. Plate 36extends beneath and serves as a support for the rear end of main section24, and it is mainly to permit the passing of this side guide or plate36 that the surface of off-set 34 is depressed and the carrier providedwith the downward extension or foot to which reference has been made. Asthus constructed the so-called squaring block aifords gaging surfaces infixed relation by means of which the side blocks are accuratelypositioned and held and the mold blade supported both within the moldblade channel and in rear thereof beneath the point of attachment of themold-blade actuating devices, and by forming said gaging and supportingmembers as integral parts of a squaring block the rigidity of the moldis correspondingly increased and liability of distortion by variationsin temperature under conditions of use is diminished.

Carrier 32 is also provided with a gage block 37 projecting through thefront stop opening in the main section and in rear of front stop 27,said gage block contacting with the rear wall of the front stop opening26 to aline the casting faces of the two mold blade sections for castingfull body type. The outer end of gage block 37 contacts with a bearing38 conveniently located on front stop 27, to assist in preventing thelateral displacement and tilting of the rear end of.

carrier 32.

The rear inner face of side block 6 together with the rear abutment onsquaring block 3 are cut away or recessed as at 6 and 3, respectivelyfor the accommodation of carrier 32 said recess in the side blocksurrounding a section 41 in the plane of the side wall of the mold bladechannel against which the point block contacts, the carrier beingrecessed as at 39 for the passage of section 41. Side block 6 is alsoprovided with a detachable cover plate 42 the inner edge of which abutsagainst cut-off section 31 above its point of attachment to carrier 32.

The top bearing for the mold blade as a whole is applied to the cut-0Esection through its carrier 32, as follows: The carrier is recessed onthe side next block 6, to provide a longitudinal bearing 43 to receivethe top bearing 44 in the form of a flanged shoe supported upon theinner end of a bolt 45 whose outer end is fastened in a recess in sideblock 6. The inner portion of the recess is larger than bolt 45 and thelatter is engaged at an intermediate point in its length by a set screw46, operating to flex the bolt and cause its inner end to press topbearing 44 into contact with the complemental bearing 43 on carrier 32,thereby holding the cut-01f section in contact with the main section andthe latter to its seat in the mold blade channel, the pressure beingdirect and extending the full length of the cut-0H section. A spring 47interposed between top bearing 44 and side block 6 serves to hold theformer to position and at the same time presses carrier 32 toward mainsection 24. To the rear end of carrier 32 is pivotally attached a lever48, provided with a spring 49 and a latch 50, the latter in a positionto engage a shoulder 51 on the cross head 30, carrying cross pin 29.referably the end of the carrier is slotted for the reception of lever48 and the latter provided with a guiding extension 52 working in saidslot to prevent displacement of the lever. The arrangement is such thatwhen the mold blade sections are adjusted to aline their casting faces,as when the main section 24 contacts with carrier block 37 and thelatter engages the front stop 27, latch 50 will be in position to passshoulder 51, and will be automatically actuated by its spring to so passthe engaging shoulder, thus locking the carrier and cut-off section tocross-head 30.

To insure the engagement of latch 50 with its shoulder 51 when the moldsections are in their extreme forward or ejecting position the opening28 in the lower or main section 24 is made slightly greater than thethickness of the cross-pin 29 so that when the latter engages the frontwall of said opening, to clamp the carrier gage block 37 against frontstop 27, shoulder 51 will slightly pass the point of latch 50 and thelatter will automatically enter behind said shoulder. If now cross head30 is retracted to dimension the mold, its movement will be communicatedthrough latch 50 to carrier 32 for the cut-01f section and through gageblocks 37 to the main section, until arrested by the engagement of themain section with the limiting or dimensioning member WVhen, however, alow quad or space is desired it is only necessary to withdraw latch 50and advance the cut-off section into the mold cavity, leaving the loweror main section 24 under the direct control of cross pin 29. Theseoperations can be performed either separately or concurrently, that isto say, separate means can be supplied for releasing the latch and foradvancing the cutoff section; but the preferred plan is one in which asingle actuating member 54 is arranged to engage lever 48 in a directionto first withdraw the latch and then, by a continuation of the motion,advance the cut ofi section, to which end a stop 55 is arranged in thepath of extension 52 to arrest lever 48. Actuating member 54 lies normally outside the path traversed by lever 48 when the sections arelocked for simultaneous adjustment, as when full body type are calledfor, and any suitable control mechanism, of which examples may be foundin Patent No. 828,450, of August 14, 1906, and application Serial No.506,550, filed July 8, 1909, may be employed to produce or govern saidactuating member and to maintain the cut-off section projected duringthe casting of the low quad or space. In the examples referred toactuating member 5% is advanced, to withdraw the latch and project thecut-off section into the mold cavity just before the cross-pin retractsto dimension the mold by seating the main section upon dimensioningmember 53.

To prevent the entrance of foreign sub stance and to supplement theaction of the top bearing, cover plate sections 56, 57, are secured tothe rear abutment, the one engaging the upper edge of the main sectionand the other the carrier 82 above their bearings upon off-set 34.
